um i must be sleeping or sumthing but i cant get this to work so some help would be ncie and maybe why it wont work

Situation: people pasting -nickname- DCC SEND blah (iphere)

we dont want the ip to be shown. so, i thought

((?i)DCC).*([0-9]{3} )\.\3\.\3\.\3

would be the regex, however its not working...
ive also tryed...

((?i)DCC).*[0-9]{3} \.[0-9]{3} \. [0-9]{3} \. [0-9]{3}
and still nothing, :S

The regexps for the IP are wrong (both times)...
Try something like

Code: Select all

DCC SEND .+ ([0-9]{1,3}\.){3}[0-9]{1,3}

Wouldn't just:
DCC SEND .+ ([0-9]{1,3}\.){3}
work fine?
(to me, that's matching 3 groups only - but it should still work fine, right? how many false positives can you expect in that kind of a case? :p)

Yeah, that would work too... I usually just try to match as much as possible...

Er... do you not realize that the IP is also included in the actual DCC request (the one that makes the "Chat/Send request" dialog pop up)? There's no point in blocking this. In fact, DCC can't work without sending the IP.

Yes, it's probably silly - afaik mIRC is the only client that sends this extra notice with DCCs, but nonetheless, once a DCC session is established, both sides can get the other's IP easily (netstat, client logging, etc).

dcc at itselfs has nothing directly todo with irc. its a client to client connection. reason most of xdcc-bottlers using proxy connection to hide their real ip. the showing of the ip in dcc transfer or dcc chat ist script based.

I believe what he's trying to block is people (for some reason) pasting this line in a channel or something? in which case he could use the 'p' target no?

@TigerKatziTatzi: That's pretty much irrelevant for this discussion but anyhow ;P

I didn't know there was a difference between private/channel messages. Guess you learn something every day.

and its so a non ircop user doesnt acidently paste a ircops ip that tryed to dcc them something.....

For a DCC, you should only need to have the c and p targets, as DCC's can't be sent any other way.

He's not talking about the DCC request, just the extra notice that mIRC seems to insist on sending...

Code: Select all

/spamfilter add pcnN block - Dont_paste_those_mkay. DCC (Chat|Send .*) ((\d{1,3}\.){3}\d{1,3})
